1. Deploy the open-vpn helm chart on Opensshift


    Deploying an OpenVPN Helm chart on OpenShift involves several steps, mostly around using the Helm chart resource in Pulumi and configuring it properly for deployment on an OpenShift cluster. Below, you will find a Pulumi program written in TypeScript that demonstrates how to deploy the OpenVPN Helm chart to an OpenShift cluster.

    Before running the following Pulumi program, make sure you have configured your Pulumi environment for the Kubernetes provider and that your KUBECONFIG is set up correctly to point to your OpenShift cluster.

    Here is what the program does, step-by-step:

    1. It imports the necessary packages.
    2. It creates a new Helm chart resource, specifying the chart name (assuming "openvpn" is available in the specified repo), version, and release name.
    3. The values property is used to pass custom configuration to the Helm chart. These will need to be aligned with the specific OpenVPN Helm chart's values for customization.
    4. The namespace property specifies which namespace within OpenShift to deploy the chart into. Make sure this namespace exists or the Helm chart will create it if allowed.
    5. For OpenShift, you may need to enable additional security contexts or modify the deployment strategy based on the cluster's security constraints. These modifications would be reflected in the values property.
    6. Lastly, it exports the release name.

    Here's the actual Pulumi program:

    import * as k8s from '@pulumi/kubernetes'; const openVpnReleaseName = "open-vpn-release"; const openVpnChartVersion = "5.0.0"; // Example version - use the actual chart version you need. // Deploy the OpenVPN Helm Chart. const openVpnChart = new k8s.helm.v3.Chart(openVpnReleaseName, { // Assuming 'openvpn' is the chart name in the Helm repo identified by 'repoUrl'. chart: "openvpn", version: openVpnChartVersion, namespace: "openvpn-namespace", // Make sure the namespace pre-exists or is created by the Helm chart fetchOpts: { repo: "https://your-helm-chart-repo-url/", // Replace with the actual OpenVPN Helm chart repository URL }, // Use the 'values' field to pass configuration to the chart. values: { // OpenVPN specific values you wish to customize. // These values would depend on the OpenVPN chart's available options. }, }); // Export the release name. export const releaseName = openVpnChart.releaseName;

    Please replace "https://your-helm-chart-repo-url/" with the actual URL of the Helm repo where the OpenVPN chart is hosted.

    When you run this program with Pulumi, it will reach out to your OpenShift cluster and deploy the specified version of the OpenVPN Helm chart within the openvpn-namespace namespace. You can customize the deployment by adding more configurations within the values section, which takes an object specifying overrides for default chart values.

    Keep in mind that deploying OpenVPN might require specific permissions and configurations depending on your organization's security policies and OpenShift's security context constraints (SCCs). You'll need to ensure that the service account used has the necessary SCCs applied, or you may need to modify the chart values to be compatible with your cluster's SCCs.
